The paper summarizes the authorized invention patents, device registration and the relevant published articles of acupuncture medical devices of TCM in recent 5 years, and analyzes the current status and challenges in this field. It is discovered that the optimization and substitution in diagnosis and treatment of acupuncture are involved in the development of acupuncture medical devices. The technology application of these devices are composed of traditional and emerging engineering technologies; and the theoretical guidance for their development requires the integration of traditional acupuncture principles with modern medical theories. The development of acupuncture medical devices highlights the characteristics of multidimensional integration, treatment for specific ailments, portability and wearability, painlessness and non-invasion, precision and personalization, as well as intelligent automation. Upon analysis, it is shown that in the development and product transformation of acupuncture medical devices in recent years, the theoretical principles of acupuncture of TCM have not been fully utilized yet, the transformation of patented product is low, the clinical evidence of product is insufficient, and the market competitiveness needs improvement. In the future, The theoretic guidance of acupuncture of TCM should be enhanced in the development of acupuncture medical devices, a production-education- research model with the combination of medicine and engineering be constructed, clinical verification of product be emphasized, and product development paradigms be advanced, so as to meet the demands of the medical market.

Objective:To investigate the therapeutic effect of combined extracranial-intracranial revascularization on elderly patients with symptomatic chronic internal carotid artery occlusion, and to evaluate its safety and efficacy in the elderly population.Methods:A retrospective analysis was conducted on 35 elderly patients(aged ≥60 years)who underwent combined extracranial-intracranial revascularization for symptomatic chronic internal carotid artery occlusion in the Department of Neurosurgery, Renmin Hospital of Wuhan University from January 2017 to June 2022.The clinical data during hospitalization, as well as the follow-up data within 2 years after operation, were collected and analyzed.Results:A total of 35 cases of combined extracranial-intracranial revascularization were performed on 35 patients.The age at surgery ranged from 60 to 74 years(mean age 65.5 ± 4.2 years). The incidence of reversible neurological deficits within 2 weeks postoperation was 34.3%, and the incidence of focal cerebral infarction within 30 days postoperation was 5.7%.The patency rate of the bridging vessel was 97.1% at 3 months postoperation., and the incidence of focal cerebral infarction during the follow-up period of 30 days to 2 years postoperation was 2.9%.At 3 months after surgery, computed tomography perfusion imaging showed that regional cerebral blood flow(rCBF), regional cerebral blood volume(rCBV), regional mean transit time(rMTT), and regional time to peak(rTTP)were improved compared with those before surgery.The modified Rankin scale score decreased compared to preoperative values, while the Montreal Cognitive Assessment showed improvement in cognitive function compared to preoperative levels(all P<0.05). From 6 months to 1-year postoperation, cerebral angiography showed that 38.7% of the patients had neovascularization of Matsushima grade A or grade B. No cases of cerebral hemorrhage or death was observed during the treatment and follow-up. Conclusions:Combined extracranial-intracranial revascularization is safe and effective for elderly patients with symptomatic chronic internal carotid artery occlusion, which can improve the patient′s hemodynamic disorders, prevent infarction events, and improve the patients′ neurological function and cognitive ability.

With advancements in in vitro culture techniques, the morula has emerged as a promising candidate for selective embryo transfer due to its critical compaction phase. The compaction process involves not only structural reorganization but also complex intercellular signaling mechanisms that significantly influence embryonic developmental potential and cellular fate determination. Clinical data reveal comparable live birth rates between day 4 morula transfers and day 5 blastocyst transfers, coupled with reduced in vitro culture duration. However, challenges persist regarding standardized evaluation criteria and long-term safety confirmation. Current morphological assessment methods exhibit inherent subjectivity, while emerging technologies integrating genetic screening, metabolic analysis, and time-lapse imaging show potential for enhanced selection accuracy. Personalized synchronization assessments, including endometrial receptivity analysis, may further optimize transfer protocols. This study focuses on day 4 embryo transfer, systematically reviewing its embryonic development processes, evaluation protocols, comparative outcomes of transferred embryos, and research advances in frozen-thawed embryo transfer. The study aims to deepen scientific understanding of day 4 embryo transfer and promote its adoption as a critical option in personalized reproductive medicine, thereby enhancing clinical success rates and safety.

Objective:To establish a day 4 embryo evaluation protocol by analyzing embryonic characteristics affecting blastocyst formation, and validate its clinical effectiveness.Methods:This retrospective cohort study included clinical data from 1 037 patients who underwent fresh in vitro fertilization and embryo transfer (IVF-ET) on day 4 in Center for Reproductive Medicine of Xingtai Meihe Reproductive and Genetic Hospital between January 2018 and April 2024. Morphological assessments were performed at (92±2) h post-fertilization. After excluding 1 326 embryos selected for fresh transfer, 2 723 embryos underwent blastocyst culture. To address selection bias in transferred embryos, the scoring system was primarily based on high-quality blastocyst formation rates. Multivariate binary regression analysis evaluated how day 4 developmental stage, fragmentation rate, stage-specific cleavage patterns, multinucleation/vacuolization affected transferable blastocyst formation rate and high-quality blastocyst rate. Regression coefficients determined parameter weights for high-quality blastocyst formation, establishing a day 4 embryo scoring protocol that compared outcomes across different grades. The scoring system was validated by comparing transferable blastocyst formation rate, high-quality blastocyst rate, and implantation rate among different day 4 embryo grades. All embryos were further rescored according to three previously reported evaluation schemes [Feil 2008, Gemma 2015, and European Society of Human Reproduction and Embryology (ESHRE) 2011]. The predictive values of these three day 4 scoring systems and the day 4 scoring system established in this study were compared using the area under the curve (AUC) receiver operating characteristic (ROC) curve in predicting the formation rate of transferable blastocyst, the formation rate of high-quality blastocyst, and implantation rate. Results:In the prediction of high-quality blastocyst formation, early blastocyst showed the highest influence weight compared to embryos with the ratio of blastomere numbers on day 4 to those on day 3 (BNR) <1.2 ( B=3.398, OR=29.915, P<0.001), followed by fragmentation <10% versus ≥50% ( B=1.263, OR=3.535, P<0.001), a stage-specific cleavage pattern ( B=0.903, OR=2.467, P=0.005), and absence of multinucleation or vacuoles ( B=0.797, OR=2.218, P=0.007). Using the newly developed day 4 scoring system, embryos were graded A, B, C, D, E. Transferable blastocyst formation rates were 88.57% (279/315), 76.99% (241/313), 56.11% (280/499), 40.27% (238/591) and 14.22% (143/1 005), respectively; high-quality blastocyst rates were 51.42% (162/315), 35.46% (111/313), 20.04% (100/499), 9.47% (56/591) and 3.98% (40/1 005). All inter-group differences were statistically significant (all P<0.005). Implantation rates for transferred embryos of grades A-E declined sequentially: 63.18% (381/603), 56.19% (322/573), 38.29% (54/141), 26.53% (13/49) and 9.67% (3/31). The day 4 embryo scoring system proposed in this study demonstrated significantly higher predictive efficacy for transferable blastocyst formation rate (AUC=0.812), high-quality blastocyst formation rate (AUC=0.804), and implantation rate (AUC=0.603) compared with Feil 2008 (AUC=0.797, P<0.001; AUC=0.781, P<0.001; AUC=0.585, P<0.001), Gemma 2015 (AUC=0.773, P<0.001; AUC=0.771, P<0.001; AUC=0.542, P=0.006), and ESHRE 2011 (AUC=0.710, P<0.001; AUC=0.745, P<0.001; AUC=0.592, P<0.001). We also observed the presence of pseudo-compacted embryo, whose transferable blastocyst formation rate [38.28% (49/128)] and high-quality blastocyst formation rate [7.03% (9/128)] were similar to those of cleavage-stage embryos with a BNR≥1.2. Conclusion:The established day 4 morphological assessment system reliably predicts the potential to transferable blastocyst and high-quality blastocyst, and effectively forecasts implantation rates.

AIM To explore the clinical effects of Tongfu Jiangzhuo Formula on ICU delirium patients with Internal Accumulation of Turbid Toxins.METHODS Based on Turbid Toxins theory,two hundred and ten patients were randomly assigned into control group(105 cases)for intervention of conventional treatment,and observation group(105 cases)for intervention of both Tongfu Jiangzhuo Formula and conventional treatment.The changes in clinical effects,delirium scores(CAM-ICU,ICDSC),TCM syndrome score,inflammatory factors(IL-1β,IL-6,IL-8),Raf-1,MEK-2,ERK-1 mRNA and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased delirium scores,TCM syndrome score,inflammatory factors and Raf-1,MEK-2,ERK-1 mRNA(P＜0.05),especially for the observation group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with ICU delirium due to Internal Accumulation of Turbid Toxins,Tongfu Jiangzhuo Formula can safely and effectively improve symptoms,and reduce inflammation levels and Raf-1,MEK-2,ERK-1 mRNA expressions.

Objective:To explore the safety and efficacy of intraosseous regional administration (IORA) of vancomycin for preventing infection in primary total knee arthroplasty (TKA).Methods:A total of 124 patients with knee osteoarthritis undergoing TKA between February 2024 and May 2024 at nine hospitals were enrolled. Preoperative infection prophylaxis involved either IORA (0.5 g vancomycin administered via intraosseous regional infusion before incision) or intravenous infusion (1 g vancomycin via peripheral vein). The IORA group included 15 males and 47 females with a median age of 66.5 years (range, 60.0-70.0 years), while the intravenous group included 14 males and 48 females with a median age of 66.0 years (range, 61.8-70.3 years) years. Intraoperative samples were collected including fat and synovium tissues after incision, before prosthesis placement, and after tourniquet release; distal femoral cancellous bone during femoral osteotomy; proximal tibial cancellous bone during tibial osteotomy; proximal intercondylar cancellous bone before prosthesis placement; and peripheral blood from non-infused arms at surgery initiation and after tourniquet release. Vancomycin concentrations were measured using liquid chromatography-tandem mass spectrometry. Vital sign changes were recorded from admission to 5~10 minutes post-IORA (IORA group) or post-incision (intravenous group). Follow-ups were conducted on postoperative day 1 and 3, and at 1 and 3 months, to document complications including IORA-related adverse events, periprosthetic joint infections, surgical site infections, red man syndrome, acute kidney injury, deep vein thrombosis and so on.Results:Vancomycin concentrations in bone, fat, and synovial tissue samples were significantly higher in the IORA group than in the intravenous group ( P<0.05), while vancomycin concentrations in blood samples were significantly lower in the IORA group than in the intravenous group ( P<0.05). Only 7.3%(41/558) of tissue samples in the IORA group had vancomycin concentrations below 2.0 μg/g (the minimum inhibitory concentration of vancomycin against coagulase-negative staphylococcus), compared to 59.3%(331/558) in the intravenous group (χ 2=11.285, P<0.001). In the intravenous group, 16.9%(21/124) of blood samples had vancomycin concentrations exceeding 15.0 mg/L (the threshold associated with a significantly increased risk of nephrotoxicity), while all concentrations in the IORA group were below this threshold, the difference was statistically significant (χ 2=22.943, P<0.001). There were no statistically significant difference ( P>0.05) in vital signs changes before and after vancomycin administration between the two groups. Two patients in the intravenous group experienced incision exudate, while no other related complications occurred in either group. Conclusions:Compared to the traditional intravenous infusion of 1 g vancomycin, intraosseous injection of a low dose (0.5 g) of vancomycin achieves higher local tissue concentrations in the knee joint with a lower incidence of adverse reactions and is safe for infection prophylaxis. Despite guidelines not recommending the routine use of vancomycin for preventing infection after primary TKA, intraosseous injection of 0.5 g vancomycin may be considered intraoperatively for primary TKA in the following scenarios: patients in medical institutions with a high prevalence of methicillin-resistant staphylococcus aureus (MRSA) infections, patients with potential preoperative MRSA colonization, or patients with cephalosporin allergy.

PANoptosis is a newly defined type of programmed cell death (PCD), which is triggered by a variety of stimuli and covers three known forms of PCD: apoptosis, pyroptosis and necroptosis. In physiological state, cell death plays an important protective role against pathogen invasion, but its over-activation may aggravate inflammatory response and cause tissue damage. Studies have shown that the occurrence and progression of acute lung injury/acute respiratory distress syndrome (ALI/ARDS), asthma, chronic obstructive pulmonary disease (COPD) and other lung diseases are closely related to PANoptosis. The purpose of this review is to deeply explore the molecular mechanism of PANoptosis and its regulatory factors in lung diseases, in order to discover potential therapeutic targets and provide new targets and innovative ideas for clinical treatment for lung diseases.

Kidney-Yang deficiency syndrome is a common geriatric disease that underlies chronic conditions such as diabetic nephropathy, chronic kidney disease, and osteoporosis. As age progresses, the kidney-Yang deficiency syndrome showcases increasingly pronounced manifestations, emerging as a key factor in the comorbidities experienced by elderly patients and affecting their quality of life and overall health status. Traditional Chinese medicine(TCM) has been extensively utilized in the treatment of kidney-Yang deficiency syndrome, with Epimedii Folium, Cinnamomi Cortex, and Lycii Fructus widely used in clinical settings. Despite the complexity of the molecular mechanisms involved in treating kidney-Yang deficiency syndrome, the potential therapeutic value of TCM remains compelling. Delving into the mechanisms of TCM treatment of kidney-Yang deficiency syndrome by regulating the neuro-endocrine-immune system can provide a scientific basis for targeted treatments of this syndrome and lay a foundation for the modernization of TCM. The pathophysiology of kidney-Yang deficiency syndrome involves multiple systems, including the interaction of the neuro-endocrine-immune system, the decline in renal function, the intensification of oxidative stress responses, and energy metabolism disorders. Understanding these mechanisms and their interrelationships can help untangle the etiology of kidney-Yang deficiency syndrome, aiding clinicians in making more precise diagnoses and treatments. Furthermore, the research on the specific applications of TCM in research on these pathological mechanisms can enhance the international recognition and status of TCM, enabling it to exert a greater global influence.
